下面是生成8位纯数字UUID的完整代码示例: importjava.util.UUID;publicclassShortUUIDExample{publicstaticvoidmain(String[]args){UUIDuuid=UUID.randomUUID();StringoriginalUUID=uuid.toString();System.out.println("Original UUID: "+originalUUID);StringhexUUID=originalUUID.replace("-","");longdecimalUUID=Long...
除了使用replaceAll()方法,我们还可以使用Java8的Stream API来获取纯数字的UUID。 importjava.util.UUID;importjava.util.stream.Collectors;publicclassUUIDExample{publicstaticvoidmain(String[]args){UUIDuuid=UUID.randomUUID();StringuuidString=uuid.toString();StringnumericUUID=uuidString.chars().filter(Character:...
